HEADREST ATTACHMENT FOR BEDS.

Specification of Letters'PaItent." Pate te S pt 2 9 Appli'cationfiled April '1, 1920; SerialNo; 370,400?

To all whom it may. concern:

Be it known that I, ANGUS MACDONALD, a residing at Melrose, in the county of Middlesex and State of Massachusetts, have invented new and useful Im rovementsin Headrest-Atis a specification.

This invention relates to an ordinaryv bed which includes abed frame or supporting structure, and a spring frame supportedby said structure and provided with a SPI'lIlg bottom, adapted to yieldingly-sustain a mattress.

The invention has for its object to provide, as-anattachm'ent for an ordinary bed including the elements above mentioned, a re'st adapted -to support the head and shouldersof the occupant in-an inclined position whenthis is desired, so that the occupant mayflie -either horizontally, or with the upper portionof the body more or less inclined, the: attachment being applicable to the bed withoutlchange in, or modification of the-latter. f

The invention is embodied in the improvements' which I will now proceed to describe and claim.

Of the accompanying drawings forming a art of this-specification,

igure 1 is; a top plan view of a bed.

provided with an attachment embodying the invention. v

Fig: 2 is a side view, portions of the bed frame-'being -broken away.

Fig. 3 is a section on line3-3 of Fig; 1, portions being broken away.

Fig. 4 is a fragmentary sectional view, showing in section portions. of the crank shaft, and the nut and sleeve hereinafter described. 1

Fig. 5 is a section on line 5-5 of'F gnl. Fig, 6 is a section on line 66 of F g. 2. Fig. 7 is a section on line 7-7, of Fig. 3. The same reference characters indicate the same parts in all of the figures.

In the drawings, 12, 12 represent the longitudinal side bars of a bed frame which may be of any suitable form and construction. There is nothing new in theconstruction of the frame here shown, and the bars 12 may be cylindrical rods ortubes, as usual,

and are "suitably rounds and is attached to the'springbed' bottom 16, and is hereinafter "called-the The fram'e'lo and bottomspring frame. 16 embody nothing new "with me, and may be of any suitableconstruction; the'fra'me belng preferably composed of bars which are angular or L-shaped in crosssection.

My improved attachment is designed for engagement with the transverse end bars of the spring frame 15, and-with theside bars 12 of the bedframe, without change or modification of said parts, and'isconstructed as next described To the end bars of the spring frame *15'are secu'red angular brackets, each composed of an'outer member 16, and an inner member 17,these members conforming' to the said end bars as shown by Fig. 3, and being clamped thereon by bolts 18 having suitableheads' and nuts. Said brackets project downwardly from the spring frame at opposite' ends of the latter, and have apertures in their lower portions, constituting bearings for a crank shaft, extending lengthwise of the bed and spring frames.

A portion of said shaft is formed by a preferably tubular section 19, journaled in one of the brackets, and provided with a crank 20. Another portion of the crank shaft is formed by a screw-threaded section 21, rigidly attached at one end to the section 19 by an internally threaded coupling sleeve 22, engaged with externally threaded meeting portions of the sections 19 and 21, as shown by Fig. 1, the threaded section 21 being provided with a reduced portion 23,

'(Fig. 3), journaled in the otherbracket;

The attachment includes a hinged portion support, adapted to sustain the head portion of a mattress, the main portion of which rests on the spring bottom 16,- andto be ,inclined at various angles, to incline the 26, and a spring filling orbottom 27 which may be of the same construction as'the attached to theme poi The arms 30 are provided with horizontal shanks 34, which are attached by bolts 35 to a channeled transverse bar 36, the cross sectional form of which is shown by Fig. 4. To the central portion of the bar 36 is attached by bolts 37, a sleeve or journal-box 38, in which the section 19 of the crank shaft is journaled, said sleeve being provided with ears 39, (Fig. 5), through which the bolts 37 pass, and the bolts being provided with clamping nuts 40 bearing on opposite sides of said ears. The sleeve 38 constitutes an intermediate support of the crank shaft, preventing the latter from springing between its end portions which are journaled in the bed frame brackets 16, 17, formed by the members.

With the threaded section 21 of the crank shaft is engaged a nut 44, with which is connected by a neck 45 (Fig. 7), a split sleeve 46, having cars 47 adjustably connected bv bolt 48. In the sleeve 46 is journaled a rock shaft 49, having arms 59 at its opposite ends, to which arm extensions or struts 51 are secured by bolts 52. The outer ends of said struts are connected by pivot bolts 53 to the arms 26 of the head rest frame.

It will now be seen that rotation of the crank shaft changes the position of the nut 44 in such manner as to cause the struts 51 to vary the position of the head rest frame, and that said frame may be adjusted to cause its spring bottom or filler 27 to lie either substantially in the plane of the spring bottom 16, or in a plane substantially at right angles to that of the bottom 16, or in planes variously inclined. It will also be seen that the attachment may be installed by securing the end brackets formed by the members 16 and 17, to the end members of the spring frame, then securing the ears 29, and cross bar 36, to the side bars 12 of the bed frame, then assembling the parts of the sectional crank shaft, after applying the nut 44 to the threaded section 21, the crank shaft being suitably mounted in its several bearings, then inserting the rock shaft 49 in the.

split sleeve 46, and finally connecting the struts 51 with the ends of the rock shaft. and with the arms 26 of the head rest frame. The journal portion 23 of the crank shaft is provided with a reduced screw-threaded extension 55, having a nut 56, said nut and the adjacent end of the portion 21 bearing on opposite sides of the bracket in which the portion 23 is journaled, and preventing endwise movement of the crank shaft.

The rock shaft 49 is preferably a half round or semi-cylindrical bar, inserted and adapted to turn freely in a tube 57, which is fixedly secured in the split sleeve 46.

I claim:

1. A head rest attachment, comprising a pair'of brackets adapted to be fixed to the end bars of a spring frame, and provided with downwardly projecting portions having crank shaft bearings, a head rest composed of a frame having a transverse portion, and arms, and a resilient filling supported by said frame, ears having means for engagement with the side bars of a bed frame,and hinged to the arms of the head rest frame, a sectionalcrank shaft journaled in said bearings, and including a threaded section, a nut engaged with said threaded section and provided with a transverse sleeve, a rock shaft adapted to turn in said sleeve, and struts attached to said rock shaft and pivoted to the arms of the head rest frame.
